Without knowing exactly what you mean by "shell", I'll assume you mean the carcass of a cabinet or like structure, Mahogany is considered by many, (cabinet makers, furniture manufactures, etc.) to be one of the best furniture woods in the world.
American mahogany or "true" mahogany (Swietenia mahogoni)---the premier wood for fine furniture and cabinetwork in Europe as early as the 1600s. today, African mahogany has a solid reputation as quality wood. It's an important timber for furniture and cabinetwork, it's extensively used in laminations, especially in cold-mold process.
The cost, density, workability fall into the middle range of all woods, (low being easy, high being hard) finishing mahogany falls in the lower half of all woods, in other words, it's very easy to finish with spectacular results.

Technically, mahogany is a hardwood. Not because of its density, but because of the type of seed it produces. Hardwood trees produce seeds with some type of shell, like a walnut, apple, or oak (acorn). Softwood seeds have no shell (and are often in cones), such as pine, fir, or cedar. Generally but not always, hardwood trees are deciduous (lose their leaves seasonally), while softwood trees are evergreen.
